Application filed November 3, 1923. Serial lllmdlddhd.

or" Chicago, in the county of Cook and State of Illinois, have inventedcertain new and useful provemen-ts in Air Washers, of which thefollowing is a specification.

My present invention embodies improve ments in air washers over that setforth in my co-pending application for Letters Patent for improvementsin air washers, Serial No. 623,830, filed March 9, 1923, and like theinvention disclosed in my said application, relates generally toimprovements in air moistening, dehumidifying and purify apparatus.

ln 3, general way, the object of my present invention is substantiallythe same as that set forth in the aforesaid pending application, to wit:the production of an apparatus of the above named general character,which shall be simple and mexpensive in construction, compact in form,and highly eflicient in operation, wherein and whereby a continu onecurrent or volume of air, which may or may not previously or afterwards,have its temperature raised'or lowered, is beneficially treated andcaused to flow through a conduit or casing and be delivered to asuitable place or places for any desired purpose.

Specifically, my present invention is directed to an improvedconstruction and arrangements of arts over the structure and arrangementof the parts of the aforesaid pending application, whereby the capacityof the apparatus will be greatly auented over that of my aforesaidinvention, or,

in other words, a greater quantity of air can be treated by theapparatus embodying the resent invention and more efiiciently than y theapparatus disclosed in my Said application, without unduly increasingthe dimen sions of the parts of the device.

l accomplish the last named objects or results by an improvedconstruction of the moisture eliminating element of the invention aswell as by the arrangement and construction of certain arts of thedevice which cooperate with sai elements. v

The invention consists in certain peculiarities of the construction,novel arrangement and combination otthe various parts thereof, as willbe more readily elained and understood when read in. conjunction withthe ancornpanyin drawin in which an 'l llll lz oi wich the invention issusthat changes and modifications ma ceptible is illustrated, it beingunderstood be resorted to without departing from t e spirit of theinvention so 10 the scope of the appen ed claims.

orresponding numerals of reference refor to like parts throughout thediilerent views of the-drawings.

'lhe conduit or casing of the device is designated as a whole by thenumeral 10 and is herein shown as being rectangular in cross-section andof an elongated shape. This casing may be made of any suitable size andmaterial but by preference of sheet metal and has its inlet end openfrom its top to a the.

point at a desired distance above its bottomor floor as at 10, see Fig.l of the drawings. By terminating the opening in the trout end of thecasing at. a distance above the bottom thereof, it is apparent that acompartment for holding water 11 will he provided at the lower portionof the casing. charging end of the casing is provided with an inwardlyextended" flange 12, the free edge of which forms an opening 13 forcommunication with a blower casin. designated as a whole by the numeralit w ich may be suitably mounted on the end of the we ing it) but forcommunication therewith as above its will be observed in 1 ol thedrawings, the casing to is provided rearwardly all lllll The llll

its longitudinal middle with a transverse partition 15, thereby dividingthe casing 10 into two chambers or compartments 16 and 17, the latterbeing of less depth than the former or front compartment and has itsfloor forwardly and downwardly inclined from the front portion of theblower casing 14 as at 18, see Fig. 1, to the rear wall of thecompartment 16 to which said floor is secured at a point a suitabledistance above the floor of the chamber 16 for the purpose to bepresently explained.

Just above the floor 18 and at the front edge thereof, the partition15\is provided with one or more openings 19 for the passage of waterfrom the inclined floor 18.to the container 20 for water in the lowerportion of the chamber 16, which container has vertically mountedtherein at about its middle an overflow pipe 21 for the discharge ofwater when a suflicient quantity thereof has accumulated in thecontainer 20 to enter the upper end of said pipe.

Transversely journaled in the blower casing 14 and'extended through thecasing 10 is a rotary shaft 22 which is journaled at its end oppositethe blower casing 14: on the upper portion of a standard 23 which may besupported on the floor of the chamber '16 of said casing. This shaft maybe driven by any suitable means but in the present instance is shown asbeing equipped at its end adjacent the blower casing 14 with a pulley 24to which a belt may be applied for transmitting power thereto from anysuitable source.

Mounted on the shaft in the blower casing is a fan 25 of any preferredconstruction, which is employed to create and maintain a current orvolume of air through the conduit orcasing of the apparatus and toforcesaid current through an outlet 26 of the blower casing, from whenceit may be conducted to any suitable place or places and used for thedesired purpose.

One of my improved water or moisture eliminating elements is mounted inthe compartment 16 of the casing and comprises a hub 27 secured to theshaft 22 so as to ro- -tate therewith and having a series of blades orvanes 28 radially extended therefrom and set at angles diagonall'disposed with respect to the shaft 22, is employed for removing moistureand impurities from the a rearward annular extension 30 which closelysurrounds yet without contacting therewith, a forwardly extended annularflange 31 on the front surface of the partition 15, which flangesurrounds an opening of its size in thesaid partition as will be readilyunderstood by reference to Fig. 1 of the drawing, in which View it willbe seen that the rear edges of the outer p01" tions of the blades 28terminate short of the rear end or edge of the rim 29, or in otherwords, are located just in front of the front edge of the flange 31carried by the transverse and vertical partition-15. Mounted on'theinner surface of the rim 29 at the rear edges of the blades 28, is anannular cleat or bafiie member 32 which is inclined forwardly as isclearly shown in F igs.,1.and 4 of the drawings whereby an angulartrough-like structure will be provided around the inner periphery of therim 29 just forwardly of the front end of the flange or annulus 31. Onthat side of each blade 28 adjacent the cleat or baiiie member 32 aseries of spaced fins or ribs 33 are longitudinally secured in such away as to have a slight inclination towards the member 32 yet so -as tobe disposed at acute angles to the surface of the blade 28 on which theyare mounted, these acute angles bein located on that side of the members33 a jacent the front end of the rim 29 of the eliminator wheel. Mountedon the opposite surface of each of the blades 28 and longitudinallythereof are a series of spaced fins or ribs 34 which are disposed atsubstantially right angles to the front edge or end of the member 32 yetso as to form acute angles between said members 34 and the adjacentsurface of the blade 28 on which they are mounted. The above namedconstruction is clearly shown in Fig. 4, in which view it will beobserved that the adjacent edges of the members 33 and 34 are sodisposed and secured to the blade 28 as to form corners of rectangularfigures when viewed in cross-section. At the apex of each of thesefigures the rim 29.is provided with an opening 35 each of which openingsis of sufficient size to be common to the angular spaces on each side ofthe blade 28 or in other words of suchsize as to provide an outletthrough the .rim 29 on each side of said blade.

As shown'in Fig. 3, the fins or ribs 34 of each blade 28 are spacedsubstantially in parallelism with one another and on account of the fanshape of the blades 28, the intermediate ribs or fins are consecutivelyshortened so that they can be thus positioned on the blades. The samearrangement is carried outwith reference to the fins or ribs 33 on theopposite side of each blade.

Mounted on suitable brackets 36 extended upwardly from the floor of thechamber 17 of the casin 10 is a cone-shaped water eliminating e ement 37which is by preference hollow and made of sheet metal. This cone-shapedmember surrounds the shaft 22 concentrically as shown in Fig. 1 directlyin front of the opening 13 in the flan e 12 of the rear end of thecasing 10 an has its front tapered end located at the rear end of theflange 31 and concentrically therewith. The member 37 has at itsenlarged upper rear portion an outwardly and forwardly disposed flange38 located eccentrically with res ect to the axis of the member 37 aswil be readily understood by reference to Fig. 2 of the drawing. Thelower portion of the coneshaped member 37 is provided at its rear edgewith a forwardly and inwardly extended flange 39, which flange, togetherwith the lower rear portion of the member 37, forms a trough-likereceptacle for the collection and guidance of water collected by theflange 38 and the upper side portions of the flange 39. Communicating atone of its ends with the trough or receptacle provided by the flange 39is a pipe 40 which 15 extended at its other end through the opening 19in the partition 15 just above the floor 18 of the rear chamber of theconduit or casing. This pipe 40 also extends through an openin in abaffle 41 located on the floor 18 of t ierear chamber of the casinrearwardly of the partition 15 and said afie is employed to preventwater discharged by the pipe 40 being forced back into the said chamber.

Mounted on the shaft 22 near its front end, is a spraying wheel which isquite similar to the spraying wheel shown and described in my aforesaidpending application, and is designated as a whole iy the numeral 42 andcomprises a hub 43 which may be fixed to the shaft 22 so as to rotatetherewith, by any suitable means. Extended radially but forwardly fromthe hub, or rather towards the inlet end of the casing orconduit, are alurality of spaced spokes 44 which are united at their outer portions bya band 45 which has the same inclination as the spokes 44 and isprovided on its inner surface with a series of diagonally disposedspaced blades 46, (see Fig. 5) which extend inwardly from the band 45and forwardly thereof towards the inlet end of the conduit or casing asis clearly shown in Fig. 1 of the drawing. The inner edges of the blades46 terminate a distance from the shaft 22 and it will be understood fromthe above description that the spraying wheel is of an overhanging type..Mounted around the shaft 22 preferably within the space provided by theoverhang ing blades 46 of the spraying wheel, is a water distributing orejecting member 47 which is preferably in the form of a tubular ring andhas in its outer periphery a series of small perforations 48 for thedischarge of water from said ring or member. This water distributor orejector is supported in a fixed position around the shaft. 22 butindependently of its movement by means of a water supply pipe 49 whichhas communication through one of its ends, with the member 47 and at itsother end with a supply of water under pressure not shown. This supplypipe may be sup ported on the standard 23 which supports one end of theshaft 22 by being extended through a suitable opening in the upper endof said standard.

The operation of the device is as follows:The shaft 22 carrying the fan25 and the rotary eliminator so as to rotate with said shaft, is drivenas before stated. by power applied through any suitable means butusually by means of a belt supplied to the pulley 24 on said shaft. Therapid rotation of the fan and rotary eliminator will create and maintaina continuous current of air entering the inlet end of the conduit,through the same, and said conduit will be dischar ed from the fancasing 14 through its outlet 26 from whence it may be conducted to anysuitable point or places. In this operation it is evident that thespraying wheel 42 will also be rapidly rotated by means of the saidshaft. Now, assuming that a supply of water under pressure is admittedto the water distributing or ejecting member 47. it is manifest that itwill be forced through said distributor in radially disposed jets orsmall streams with which the blades 46 of the spraying wheel willcontact and act to force the water in spray or mist-like conditioncircularly at the inlet end of the casing or conduit As the blades 46 ofthe spraying wheel 42 areydiagonally disposed on the inner surface ofthe band 45, which band is flared towards the inlet end of the easing,the water will be more effectually driven forwardly by the action ofsaid wheel than if the said bladeswere located radially on said band, asin my above named application. The current of air passing into theconduit will be subjected to theispray or mist-like sheet of watercreated by the rapidly rotating spraying wheel 42, and will absorb aquantity of the same. In the further progress through the casing of theair, it will contact with the rotating blades 28 and the fins 33 and 34-on opposite sides pf each of said blades and through centrifugal action,the water and impurities will be forced outwardly along the surfaces ofthe blades 28 and adjacent surfaces of the fins or ribs 33 and 34 untilthe rim 29 of the wheel is reached, from whence they will pass throughthe openings 35 therein and be discharged into the chamber 16 andprecipitate into the water container 20 of said chamber.

- After the air has been subjected to the action of the blades 28 andtheir fins or ribs, the current thereof will pass through the openingprovided by the flange 31 in the partition 15 and impinge against theconeshaped water eliminator 37 on which it will travel rearwardly andoutwardly from the tapered portion of said member until it strikes theflanges 38 and 39, from which it will pass around the enlarged end ofthe coneshaped eliminator and rearwardly out through the opening 13 inthe rear end of the casing and from thence into the fan from which itwill be discharged through the outlet of the latter. In this operationof the current of air on the cone-shaped eliminator, it is manifestthatmoisture or water contained therein will be extracted therefrom andcaused to collect in the trough-like portions provided by the flanges 38and 39, from the latter of which the water will be. drained through thepipe 40 into .mounted on and to rotate with said shaft within saidcasing said wheel comprising a plurality of spaced radial blades eachset at an angle to its axis and provided with a peripheral rimconnecting the outer ends of said blades, the said rim having aplurality of spaced openings arranged in a row at the outer end of eachof said blades, said openings being of sufiicient size as to each affordoutlets on opposite sides of each of said blades, a plurality of spacedfins longitudinallymounted on each surface of each of said blades andconnected at their outer ends to the inner surface of said rim, the saidfins being disposed at acute angles in the direction of the rotation ofthe wheel with respect to their blades and connected to the same inpairs at the rear portion of each of said openings in the rim, and aforwardly inclined annular cleat or baflle member secured to the innersurface of said rim at the rear outer portions of said blades, said rimhaving a series of spaced open-o ings at the adjacent edge of saidbaflle.

2. An air washer including a casing for the passage of air and a.rotatable shaft located longitudinally therein means in communicationvwith an end for creating and maintaining a current of air through thecasin an imperforate cone-shaped moisture e iminatin member fixedlymounted within said casi in front of its disdischarge opening wit itstapered end disposed forwardli of said casing, said member having at t eupper rear portion of its periphery a forwardly and outwardly extendedfiangle and at the rear lower portion of its peri cry a forwardly andinwardly extended ange forming a trough-like receptacle on said lastnamed ortion of said member, and a ipe extend at one of its ends throught e last named flange for draining water therefrom.
